I can go the distance, says Tomic

Fuelled by adrenaline and with his confidence sky high, Bernard Tomic is poised to continue his white-hot summer form at the Australian Open.

Roger Federer looms as a hazardous third-round road block, while eight matches - for eight splendid wins - in a fortnight must have taken a physical and mental toll.

Tomic, though, says he's well prepared for the rigours of five-set grand slam tennis and believes he'll take a power of stopping at Melbourne Park.

"Best-of-five is always difficult. You don't know how your body can pull up, but I think I'm pretty fit. Not a lot of problems," he said on Sunday ahead of his first-round clash on Tuesday with Argentine Leonardo Mayer.

"I played five straight matches in Sydney. I had no problem after the tournament, so I feel physically fine. I'll be ready for five sets any day of the week."

Tomic was still buzzing from Saturday night when he became the first 20-year-old since Federer in 2002 to reign in Sydney.

The breakthrough sent Tomic rocketing from 64th in the rankings to back inside the world's top 45.

He arrived at Melbourne Park with his Australian No.1 status restored and said his stunning transformation from perennial first-round loser in the second half of 2013 was mainly a result of his vastly improved conditioning.

"It's just amazing what I've done the last few months and got my body to where it is," he said.

"And my tennis is improving each day. I can feel it.

"To get all these matches under my belt is big confidence. This is what you need in this sport: confidence.

"I'm going to approach (the Australian Open) very differently now. Now I'm confident and know I can do well, and I'm going to push as much as I can."

The former Open junior champion believes "anything" is possible over the next fortnight.

"When you know that no one can beat you, not even the No. 1, you've got a good feeling.

"It's amazing stepping on court. You're so confident."

Tomic even risked stirring up Federer, saying he "saw the papers this morning" and how the four-time Open champion had warning him not to start preparing for their projected third-round match-up just yet.

"Well, if he gets that far," said Tomic, subtly returning serve to the Swiss maestro.

"I mean, the first round is my goal, to beat this guy. I do struggle against some guys out there.

"I don't know how this guy can play. If the possibility comes for me to win that first match, I'll look for my next round, which is also tough.

"I would love to get in that position to play Roger in the third round. He has to get there as well. You don't know what can happen. Tennis is a funny sport. So we'll see."
